A CCTV jammer is a device that emits electromagnetic radiation in the same frequency range as a camera’s wireless transmitter, disrupting the camera’s operation. Jammers are illegal in many countries and their use can result in fines or jail time.
CCTV cameras are becoming increasingly common, as they are an effective way to deter crime and monitor public areas. However, there are some people who object to their use on privacy grounds. In response, some people have begun using jammers to disable the cameras.
Jammers work by emitting a signal that interferes with the camera’s wireless transmitter, preventing it from sending or receiving data. This effectively renders the camera useless. While jammers are illegal in many countries, they are readily available for purchase online.
